The operating system transfers the network characteristics to the user application. The user application selects one of multiple wireless communication networks based on the network characteristics. The wireless network circuitry wirelessly exchanges user data for the user application with the selected wireless communication network.

TECHNICAL BACKGROUND

Wireless communication networks provide wireless data services to wireless user devices. Exemplary wireless data services include machine-control, internet-access, media-streaming, and social-networking. Exemplary wireless user devices comprise phones, computers, vehicles, robots, and sensors. The wireless communication networks have wireless access nodes which exchange wireless signals with the wireless user devices over radio frequency bands. The wireless signals use wireless network protocols like Fifth Generation New Radio (5GNR), Long Term Evolution (LTE), Institute of Electrical and Electronic Engineers (IEEE) 802.11 (WIFI), and Low-Power Wide Area Network (LP-WAN). The wireless access nodes exchange network signaling and user data with network elements that are often clustered together into wireless network cores. The wireless access nodes are connected to the wireless network cores over backhaul data links.

The wireless access nodes comprise Radio Units (RUs), Distributed Units (DUs) and Centralized Units (CUs). The RUs are mounted at elevation and have antennas, modulators, signal processor, and the like. The RUs are connected to the DUs which are usually nearby network computers. The DUs handle lower wireless network layers like the Physical Layer (PHY) and Media Access Control (MAC). The DUs are connected to the CUs which are larger computer centers that are closer to the network cores. The CUs handle higher wireless network layers like the Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP). The CUs are coupled to network elements in the network cores. Exemplary network elements include Access and Mobility Management Functions (AMFs), Session Management Functions (SMFs), and User Plane Functions (UPFs).

The wireless user devices comprise user circuitry and wireless network circuitry. The wireless network circuitry has radios and network applications to communicate over the air with the RUs in the wireless access nodes. The user circuitry has an operating system and user applications that use the wireless network circuitry for external data communications. The wireless network circuitry receives and processes wireless signals from the wireless access nodes to develop network characteristics for wireless communication networks. The network characteristics describe wireless network types, wireless signal qualities, Public Land Mobile Network (PLMN) features, wireless network slice parameters, UE antenna configurations, Radio Resource Control (RRC) status, System Information Block (SIB) broadcasts, and the like.

To optimize network communications, a user application in a wireless user device calls its operating system for information that indicates wireless network types and their wireless signal qualities. In response to the call, the operating system transfers a request for the wireless network types and their wireless signal qualities to the wireless network circuitry. The wireless network circuitry responds to the operating system with the wireless network types and their wireless signal qualities. The operating system transfers the wireless network types and their wireless signal qualities to the user application. The user application selects a wireless communication network based on the wireless network types and their wireless signal qualities. The user application then transfers a call to the operating system for the selected wireless communication network. The operating system transfers a request for the selected wireless communication network to the wireless network circuitry. The wireless network circuitry exchanges user data for the user application with the selected wireless communication network.

Unfortunately, the user application does not have access to detailed network characteristics like PLMN features and network slice parameters when selecting its wireless communication networks. Moreover, the user application does not optimize its network communications based on detailed network characteristics like PLMN features and network slice parameters.

FIG. 8 further illustrates 5G wireless network core 421 that serves 5G UE 401 which optimizes network communications for user application 405.

FIG. 9 illustrates the operation of 5G UE 401 to optimize network communications for user application 405. The operation is exemplary and may vary in other examples. In wireless UE 401, operating system 404 directs a graphic display to prompt a user to obtain the user's express permission for user application 405 to access network characteristics for RANs 411-413. Operating system 104 receives a user instruction through the display to permit user application 405 to access the network characteristics. The network characteristics comprise radio signal metrics, PLMN features, wireless network slice parameters, UE antenna configurations, RRC information, SIB data, and the like. For example, the RRC data may indicate received signal power and interference metrics for RANs 411-413.

To optimize network communications, user application 405 transfers a call to operating system 404 for the network characteristics. In response to the user permission and the call, operating system 404 transfers a request for the network characteristics to the RRC for radio 407. The operation of the RRC for radios 408-409 is similar. The PHY in UE 401 detects the network characteristics from the downlink symbols provided by radio 407 and transfers the network characteristics to the RRC. The RRC responds to operating system 404 with the network characteristics. Operating system 404 transfers the network characteristics to user application 405.

User application 405 selects one or more of RANs 411-413, wireless network slices, and/or PLMNs based on the network characteristics. In this example, user application 405 selects RAN 411, PLMN A, and wireless network slice B. User application 405 transfers a call to operating system 404 for RAN 411, PLMN A, and slice B. Operating system 404 transfers a request for RAN 411, PLMNs A, and slice B to the RRC that interacts with RAN 411. The RRC in UE 401 exchanges signaling with the RRC in CU 451 to establish the wireless data service using PLMN A and slice B. The RRC in UE 401 exchanges signaling with the AMF 771 in core 421 to establish the wireless data service using PLMN A and slice B. AMF 771 interacts with UDM 772 to authenticate UE 401 and authorize PLMN A for UE 401. AMF 771 interacts with NSSF 772 to authorize slice B for UE 401. AMF 771, PCF 774, and SMF 775 interact to select the remaining UE context like QoS and network addresses for the wireless data service over PLMN A and slice B. AMF 771 directs the RRC in CU 451 to serve UE 401 per the UE context. SMF 775 directs UPF 776 to serve UE 401 per the UE context.

In UE 401, user application 405 exchanges user data with operating system 404, and operating system 404 exchanges the user data with the SDAP for radio 407. The SDAP for radio 407 and the SDAP in CU 451 exchange the user data per the UE context which requires PLMN A and slice B. The SDAP in CU 451 and UPF 776 exchange the user data per the UE context using PLMN A and slice B. UPF 776 exchanges the user data with external systems per the UE context using PLMN A and slice B.

The wireless data network circuitry described above comprises computer hardware and software that form special-purpose UE circuitry to optimize network communications for user applications. The computer hardware comprises processing circuitry like CPUs, DSPs, GPUs, transceivers, bus circuitry, and memory. To form these computer hardware structures, semiconductors like silicon or germanium are positively and negatively doped to form transistors. The doping comprises ions like boron or phosphorus that are embedded within the semiconductor material. The transistors and other electronic structures like capacitors and resistors are arranged and metallically connected within the semiconductor to form devices like logic circuitry and storage registers. The logic circuitry and storage registers are arranged to form larger structures like control units, logic units, and Random-Access Memory (RAM). In turn, the control units, logic units, and RAM are metallically connected to form CPUs, DSPs, GPUs, transceivers, bus circuitry, and memory.

In the computer hardware, the control units drive data between the RAM and the logic units, and the logic units operate on the data. The control units also drive interactions with external memory like flash drives, disk drives, and the like. The computer hardware executes machine-level software to control and move data by driving machine-level inputs like voltages and currents to the control units, logic units, and RAM. The machine-level software is typically compiled from higher-level software programs. The higher-level software programs comprise operating systems, utilities, user applications, and the like. Both the higher-level software programs and their compiled machine-level software are stored in memory and retrieved for compilation and execution. On power-up, the computer hardware automatically executes physically-embedded machine-level software that drives the compilation and execution of the other computer software components which then assert control. Due to this automated execution, the presence of the higher-level software in memory physically changes the structure of the computer hardware machines into special-purpose UE circuitry to optimize network communications for user applications.
